A buddy of mine used his friend’s 28 a few weeks back to see if it was what he wanted to upgrade to. He just got an LX 7 and has been very happy he decided to go Marcum.
I was in your boots a little over a month ago as well and after using the lx5, lx6, and lx7 there’s no way I would get the FLX28. I’m not trying to say it is a bad unit, or start a vex/Marcum brawl, but the features of the LX 7 massively outweigh what the FLX28 brings to the table and they’re in the same relative price range. I have been a Vex guy since the first day my foot hit the ice, but Marcum really stole my heart, you wouldn’t be dissapointed one bit.
